(3 × $0.216 + $0.647) ÷ 4 = $0.323/1M — the $/1M figure blends input and output at 3:1 — that is the only way models with two different rates can be ranked on one axis. Your actual rate depends on your own input:output mix — input only $0.216, 3:1 $0.323, 1:1 $0.431, output only $0.647 per 1M.
The board shows this model's cheapest measured offer ($0.323/1M); the smaller figure under it is the mean of the 8 offers listed below ($0.550/1M). Add those up and divide — it matches.
